Vacuum Tubes

AMPEREX - PM 2412B PMT Tube.

Photomultiplier (PMTs) and phototubes are light-detecting tubes used in electric eyes, video cameras and various astronomical applications. Phototubes are simple devices, often gas-filled, consisting of a photocathode and anode. PMTs are more complex high-vacuum devices.

The Amperex PM-2412B is a top-sensing 10-stage linear cascade photomultiplier with a venetian blind aperture and a 3" window. The PM-2412B is intended for use in gamma cameras and other scintigraphy applications.
